In this interview with [Gibson.com](http://www2.gibson.com/News-Lifestyle/Features/en-us/The-Script-Mark-Sheehan.aspx), Mark talks about his collection of guitars and why, for him, Les Paul's are the only way to go.
As he mentions in the interview, Mark plays a 2008 Les Paul Standard Goldtop, which he plays for songs such as "Breakeven".
